| titleOfInvention | The method of purification of longifolene |
| abstract | The present invention discloses a kind of method of purification of longifolene, belongs to turpentine oil deep process technology field.The present invention includes first being reacted pending longifolene with solid phosphoric acid catalyst, and the material for obtaining reaction is evaporated under reduced pressure to obtain longifolene crude product, then it is transferred in another reactor, add acetum, hydroquinones and p-methyl benzenesulfonic acid, are stirred, after stopping stirring, standing separation goes out material bed, and obtained material is then carried out into rectifying after washing.The present invention has gentle reaction condition, technique and simple flow, using the advantages of equipment is few, cost is low, and using the present invention, the purity of longifolene product can be made to reach more than 90%. |
